For a tanky Tel I'm not sure I would use Gonk. The point being you are essentially making it less likely to use his ability so you may as well use another ship. Sure you have the benefit of regenerating after you revive, but you have spent a lot of the game trying to avoid that. I know it is enticing to imagine a scenario where you would end up back at 5 or 6 HPs but it is not all that likely to happen.
Why would you wait that long to regen? Once Tel's ability kicks in you are back to having 1 or 2 remaining hit points depending on if you took a HU or not. Instead of being dead you are nearly dead. What if your opponent has more attackers and you don't live to the next round?
The value here is in just how many bonus hit points you buy yourself with hull and/or Gonk. That's the way it looks on paper right now. Who knows where we end up in terms of a near optimum setup. We probably won't know for sure for a good 2-3 months when something emerges during Regionals. Or maybe someone shows up with a list using it a certain way at Gencon that changes how everyone wants to play it from that point on.
